EEG Relationships to Neural Aging in the Elderly: Overview and Bibliography

ABSTRACT.

The central nervous system undergoes structural and functional changes during normal aging. Associated with age-related neuroanatomical, behavioral, and sensory alterations are changes in the EEG as reflected in slowed background frequency, emergence of delta and theta waves, and focal activity in the temporal areas. The current status of age-related EEG changes is reviewed in order to provide a background for continued study on aging and brain function by EEG technologists.
